An input capture signal (pulse train) can be prescaled by N = 2-62 (in multiples of 2) or can bypass the prescaler. This is useful when very high frequency signals are used as inputs. Figure 7-248 shows a functional diagram and Figure 7-249 shows the operation of the prescale function. The event prescaler can be reset by setting the ECCTL2.CTRFILTRESET register bit.
